Definitions
- the present invention is a mold and process for obtaining a recyclable polymer bicycle frame, more precisely it is an injection molding type with injection process drawer, specially developed for making monoblock bicycle frame made of polymeric material, particularly from the recycling and reuse of PET bottles; said bicycle frame has constructive configurations endowed with resistant and flexible mechanical characteristics;
- the object of the present invention cooperates for the preservation of the environment through the use of recyclable material.
- a key item in the use of polymer to manufacture various products is the possibility of reuse of plastic through recycling, such as the recycling of PET bottles that allow the manufacture of numerous products such as t-shirts, solar panels, brooms, etc. , besides contributing considerably to the preservation of the environment and the whole chain linked to it, either by reducing the volume of waste in the landfills and improvement of the decomposition processes of organic materials, oil economy, energy saving in the production of new plastic as well as in the generation of jobs in the area of recycling and, mainly, resulting in the reduction of the values of the products that have as recycled materials.
- the current molds developed for the injection process consist of at least two parts, one part being installed on the stationary plate and the other part on the moving plate, which are interconnected by columns and guide bushings that direct the moving part to join the fixed part.
- Alignment of the two halves is critical, thus preventing any plastic leakage when injected under high pressure into the cavity, while the damping channels are predicted points between the injection port and the cavity.
- gate Another extremely important factor in the plastic injection mold is the arrangement and shape of the Injection points, also known as "gate", which correspond to the point of attack of molten material to the mold cavities, in turn, with the function of passing through the molten material.
- Injection points also known as "gate”
- gate There are several ways to apply the input channel, such as gate with rectangular restricted entry, or fan type, flap type, film input type, among others.
- Each type of gate is linked to the type of part to be extracted from the mold and therefore influences its construction.
- Another important feature of the injection point is its sizing, being necessary some care as to the shear rate and stress that should be as small as possible, but without breaking molecules or fibers.
- the location of the gate generally consists of a location that is barely visible or as close as possible to the center of the workpiece and of the largest workpiece thickness, ie it should be avoided in the most stressed or mechanically requested areas.
- the applicant active in the field of product development in thermoformed plastic, is already depositor of the document dealing with a one-piece frame designed to receive the conventional elements that make up the bicycle, such as seat support seat, high-pressure tubular frame and front front wheel fork, main ratchet, wheel rear and secondary ratchet;
- the one-piece frame is integrally molded of rigid, virgin or recycled polymer, shaped as a single piece and consists of a central spar from which identical lateral branches develop and may be opaque or translucent and with adequate pigmentation.
- the applicant developed mold and process of obtaining bicycle frame in recyclable polymer, more precisely it is a injection molding type with injection process drawer, specially developed for making one-piece bicycle frames made of polymeric material, particularly from the recycling and reuse of PET bottles; said bicycle frame has constructive configurations endowed with resistant and flexible mechanical characteristics;
- the object of the present invention cooperates for the preservation of the environment through the use of recyclable material.
- the main advantage lies in the fact that the new functional design of the mold prevents the occurrence of failures during the production of the bicycle frame, thus allowing the generation of wear, gripping or breaking of components.
- this mold allows versatility in the removal of screws, extraction of the drag pins facilitating the maintenance and, consequently, the serial production, besides promoting safety for the operator.
- Another advantage lies in the fact that at least two hundred PET bottles are used for the production of a recyclable polymer bicycle frame, which contributes to the preservation of the environment, besides presenting an extremely low cost compared to the current bicycle frames.
- Figure 1 is an exploded perspective view of the now-innovated mold
- Figure 2 shows an assembled perspective view of the mold
- Figure 3 shows a longitudinal section
- Figure 4 illustrates a cross-sectional view
- Figures 5 and 6 represent side views of the cavity holder plates
- Figure 7 shows a side view of the cavity holder plate illustrating the main drawer and secondary drawers in exploded position
- Figure 8 shows a block diagram of the procurement process
- Figure 9 illustrates a perspective view of the resulting bicycle frame.
- the present invention relates to "RECYCLEBLE POLYMER BIKE FRAME MOLDING AND PROCESSING", more precisely the mold (1) and process (PO) from which the injection process is obtained.
- said mold (1) is formed by two complementary parts, namely: a stationary unit (2) and another mobile unit (3) which, in turn, includes sliding columns (3A) in recessed guides ( 2A) provided in the stationary unit (2), with both stationary unit (2) and mobile unit (3) having base plates (2b) and (3b) for mounting respective cavity plates (2c) and (3c). ) whose complementarity conforms the structural channel (EC) to receiving the injected thermopolymer (TI) and, consequently, obtaining the bicycle frame (QB).
- the cavity holder plate (3c) of the mobile unit (3) provides a longitudinal cradle (3d) for mounting the central main drawer (GP) and laxial cradles (3e) for mounting secondary drawers (GS).
- longitudinal (3d) includes peripheral tracks (3f) for sliding the main drawer (GP), and provides a drag pin (3g) whose angularity allows the horizontal movement (MH) of the main drawer (GP), while the Side cradles (3e) also provide drag pins (3g ') for the secondary drawers (GS).
- Said main drawer (GP) is configured by an oblong part (4) whose side edges (4a) are framed by rulers (4b), while near the rear edge (4c) a cutout (4d) is made for coupling wedge.
- locking (5) provided in the cavity holder plate (2c) of the stationary unit (2), as well as the receiving channel (4e) for receiving the injected thermopolymer (TI) and flow channel (4f) for the distribution of the injected thermopolymer ( And, consequently, development of a single injection point (PI) of said structural channel (EC) whose "Central Spar" (LC) shape from which identical lateral branches (RL) are developed to obtain the bicycle (QB) monoblock.
- the central portion between the branches (RL) of the upper and lower cavities is aligned with said central drawer (GP), while at the vertices of the cane l frame 1 (CE), said secondary drawers (GS) are mounted.
- the process of obtaining (PO) the bicycle frame (QB) from recyclable polymer consists of the following steps:
- the resulting product of the obtaining process (PO) consists of the bicycle frame (QB) is ordinarily "Y" shaped monoblock forming a central spar (6) from which identical lateral branches (6a) comprising two tubular vertices develop. (6b), one being a horizontal tubular vertex 1 (6b ') for mounting the crankshaft axle (EP) and another vertical tubular vertex (6b ”) for mounting the handlebar axle (EG).
- each branch is in the form of a hook (G) where the rear wheel support axle (EX) is mounted (not shown).
